TO ALL WHOM IT MAY GONCERNz.

Be it known that I, CHARLES F. WALDltON, of the city, county, and Stateof New York, have invented certain new and useful Improvements in Lampsfor Vehicles; and I do hereby declare that the following is a fall,

clear, and exact description of the same, reference being bad to theaccompanying,drawing, makings-portion of this specification, which is acentral vertical seet io n o f a lamp or signal, constructed accordingto my invention.

This invention is more particularly designed i'oiuse as a fire-enginesignal, but may also be employed ash carriage-lamp; audits object is toenable the body of the lamp'to be attached to the supporting portions ofthe same with greater facility, and also with greater security than by'the method ordinarily employed.

The invention consists in an annular plate, furnished at its upper-edgewith asuitable flanob, and so com bined with the inwardly-turned loweredge of the lamp-body, that thesnid body will be rigidly attached to theaforesaid plate, and be th'us firmly held in place. The inventionfurther consists in the combination bi an: annular not with theai'oresaiadintcrnal plate, and a suitable external base-shell, wherebysuoh plate and shot? are securely fastened together, as required in theattachment of the body to the said parts, as. just mentioned.

To-enable others to understand the natureand construction of myinvention, I will prooeedto describe it,

with reference to the drawings.

The body of the lamp, shown at A, may be of any suitable form andconstruction, but open at the bottom,

- and with its lower edge turned inwards over an annular wire, as shownat a. A base-shell, also of any desired or appropriate form, isrepresented at B, and may be of sheet metal. Placed within this shell isan annular plate or piece, 0, which may be made of brass, and the bottomof which need not extend quite as low as that oi the shell B. Extendingupward from the upper edge 'of this internal plate,-at a little distancefrom the outer periphery thereof, is a thin fianch, b. The lower edge ofthe body A isplacod upon the upper edge of the internal plate 0, betweenthe fianch, 6, thereof, and the surrounding upper edge or rim, 0, o ftheshell B, the thumb 6 being then turned outward, so as to lap over theinwardly-turned lower edge of the body A, as represented in the drawing,and thus serving toseeurely attach the body of the lamp to the aforesaidannular-plate A. As a modification of this means of securing the body tothe annular plate, the'flaneh may have substituted for it ears or lugs,placed at suitable distances apart, and turned over the lower portionsof the body insuch manner as to clamp the same in place. I

A screw is provided in the lower part of the internal plate 0, as shownat a, and into this is screwed an annular nut, D, which is furnishedwith a flatcircumferential flange, d, which bears against ,the bottom of.the shell 0 in such a way that by tightening the nut D, the upper edgeor rim of the shell will be. pressed snugly against the outer side ofthe lower edge of the body A, the said shell being by these means heldsnugly in its place. Instead of beingscrewed into the plate D, as justset forth, the upper part thereof may be'fitted into the platc c, andconfined thereto by a transverse pin, sot-screw, or other suitablemeans.

By the means herein set forth, the body is firmly and securely attachedto the base or supporting portions of the lamp, without the use, ofsolder or bracing-ribs, as required in the ordinary method of fastening.Furthermore, by thismet hodof securing the body to the supporting partsof'the lamp, such body may be readily detached when desired.

- I The annular nut D is made preferably with a screw, 6', upon itslower portiou,-upon which a bottomplate, E, is serewed,whioh in its turnis attached to that portion of the engine or vehicle to which it isdesired to attach the lamp or signal.

What I claim as my invention, and desire to secure by Letters Patent,is- I 1. The annular internal plate 0, formed-with the fla rioh'b, incombination with the lower portion or edge of the body A, substantiallyasa'nd for the purpose herein setforth. I

2. The annular-nut D, in combination with the base-sbell B and internalplate 0, substantially as and for the purpose specified.
